CARRIER FOR BRAIDING-MACHINES.

Application filed October 27, 1919.

To all whom it may concern:

Be it known that I, STANIsLAs S. PICARD, a citizen of the United States,residing at Providence, in the county of Providence and State of RhodeIsland, have invented new and useful Improvements in Carriers forBraiding-Machines, of which the following is a specification.

This invention relates to certain new and useful improvements in acarrier for braiding machines, and it has for its primary object toprovide an improved carrier which will guide and direct itself from onechannel or guideway to the following one in a very efficient andpractical as well as proper manner.

The invention consists broadly in the provision of a two part carrierwith one part arranged slightly in advance of the other and yieldablyrelated thereto whereby the lower or rear part may have a longer bearingin the present guide or channel while the forward part is entering theadjacent guide under the direction and control of the rear part.

In the drawing:

Figure 1 is a side elevation of the improved carrier;

Fig. 2 is an end elevation thereof; and

Fig. 3 is a horizontal section therethrough on line 33 of Fig. 1,depicting the yieldable or resilient connection between the parts of thecarrier.

Referring more in detail to the drawing, the numeral 1 designates thelower part of the carrier of a braiding machine, and 2 the upper partwhich is pivotally connected by means of a vertically disposed pivotscrew 3 passed upwardly through the bottom part and threaded in the toppart whereby the one may have pivotal movement relative to the other.Each part is shaped alike so as to readily follow in the guideways,which are usually a series of communicating or intersecting circles, andthe top part is superposed on the bottom part in a slightly advancedrelation where by its nose or front end will enter the adjacent guidewayprior to the rear end of the bottom part leaving the present guideway.By this operation the proper channel or guideway will always be selectedor entered.

The parts of the carrier are formed in their opposing or hearing faces 4with sub- Specification of Letters Patent.

Serial No. 333.495.

stantially semi-cylindrical recesses 5 supplementing one another in theformation of spring chambers, one being in advance of the pivot 3 andthe other to the rear thereof. In each spring chamber is compressed acoiled spring 7 bearing in opposite directions on the end walls of thefour recesses 5. Their function is to normally hold the top and bottomparts in operative alinement, permitting them to relatively yield as theupper part enters the adjacent guideway ahead of the supporting lowerpart.

The bobbin-carrying portion 8 is secured to the stubshaft 9 which isfixed to and carried by the top part, as is clearly depicted in Figs. 1and 2.

In operation, as the carrier passes over from one circular guideway tothe next so as to bring the thread of the carrier either inside oroutside, depending upon the traverse of the carrier which is to the leftas viewed in the drawing, the bottom part, by reason of its rearwardprojection will still be guided in the present guideway while the toppart has left it and is entering the next guideway. By reason of theresilient con nection between the parts the top part will be directedinto the proper succeeding guideway in an accurate manner.

Having thus described my invention, what I claim as new and desire tosecure by Letters Patent is:

1. A carrier for braiding machines, comprising a bottom supporting part,a top bobbin-carrying part superposed thereon in slightly forwardlyoil'set relation so as to lead the bottom part, both parts shaped tooperate in the guideways of a braiding machine, a pivot pin disposedvertically and pivotally connecting the parts, the bearing faces of thelatter being formed with component chamber-forming recesses, and coiledsprings disposed in the chambers formed by the recesses for resilientlyholding the parts in proper relation.

2. A carrier for braiding machines, comprising an upper and a lower partconnected for swinging about a vertical pivot, one part being disposedin advance of the other, and means resiliently holding the partsrelatively operative.

3. A carrier for braiding machines, comprising resiliently connectedparts arranged. one in advance of the other and each formed to bereceived in the guideways.

4:. A carrier or braiding machines, com prising yieldably connectedsuperposed parts, and each formed to be received and travel in theguideways and one set for- Wardly of the other, the upper part carryingthe bobbin.

5. A carrier for braiding machines, comprising pivotally connected,relatively superposed parts each formed to be received and adapted totravel in the guideways of a braiding machine. 7

6. A carrier for braiding machines, comprising a pair of superposedparts arranged one slightly in advance of the other, and each formed tobe received and travel in the guideways and means'yieldably connectingthe parts for holdingthem operatively related.

7. A carrier for braiding machines, including relatively movable partseach formed to travel in the guideways, said parts being arranged sothat an end of each projects outwardly beyond the adjacent end of theother, and a bobbin support carried by one of the parts.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses r ,7 7
